GSC P-D 2015+ Subaru WRX FA20F Exhaust Valve - 29mm Head (STD) - SET 8 (2281-8)
In embarking on the journey to introduce our novel valve line, we embarked on the resolute mission of crafting the epitome of performance and enduring excellence within the aftermarket realm. Our quest led us to harness the power of advanced 3D design and simulation software, sculpting an evolved valve head design that stands as a testament to strength and enhanced flow dynamics. Our commitment extends to real-world validation, where prototype valve heads undergo meticulous flow testing in their designated applications. This ensures that our creation reigns as the paragon of flow efficiency among contemporary offerings. By meticulously selecting premium materials, our innovation stands apart, boasting unparalleled resistance to valve face distortion – a trait observed conspicuously absent in competing designs. This newfound stability in the face of stress translates to a peerless capacity for sealing prowess, particularly under the duress of extreme conditions. The result is a valve that orchestrates flawless harmony between sealing integrity and persistent performance, upholding its virtuosity throughout its lifecycle. The emergence of GSC Power-Division's pioneering valves is destined to usher in a new era, destined to define the benchmark for sport compact performance valves. Our relentless pursuit of excellence has yielded an indomitable testament to engineering ingenuity that is poised to shape the landscape of the industry
APPLICATIONS
- Subaru WRX (2015, 2016, 2017, 2018, 2019, 2020, 2021)
FEATURES
- Swirl polished heads for smoother air flow over the valve
- Back cut to reduce valve weight for higher RPM, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures
- Valve stems are micro-polished to allow for less oil retention on the stem, which creates less drag on the stem to guide for a smoother motion
- Intake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity
- Valve tips are either hardened or have a stelite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear
- Valve tip lengths - we have taken extra time to adjust tip heights on the applications to require less tipping of the valve, to maintain proper tip height for proper valve train geometry, and to cut down on install times when setting valve lash
- We have also adjusted the keeper groove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from our spring and retainer kits
- Valves will work with an OEM keeper/lock or, when available, our upgraded keeper/lock. It is not mandatory, but it is suggested, that any valve lock not be reused on performance applications due to material grooving
